A Luckenbooth brooch is a Scottish
heart-shaped brooch, often with a crown above one heart, or two
intertwined hearts. The brooches are typically made of silver, and
are sometimes engraved or set with stones. For the wealthier
customer, Luckenbooth brooches would be made with gold, however
silver was common among 'lucky' charms and affordable to those who
were poorer.
